The test detects eggs from roundworms, hookworms, whipworms, coccidia, and some tapworm species. A small stool sample is mixed with a flotation solution and centrifuged; eggs float to a coverslip placed on top, which is then examined under a microscope. Fecal floats are recommended at least annually for adult pets and more frequently for puppies, kittens, and animals with diarrhea. Some parasites like Giardia require antigen tests for reliable detection since their cysts shed intermittently. Combining fecal floats with year-round parasite prevention provides the best protection for your pet and family.
